Portable Density Meter
Model No. :
Model No. : DMA 35
Brand : Anton Paar
The DMA 35 is a robust, portable density meter engineered for high-accuracy density and concentration analysis directly in the field, replacing less precise and fragile glass hydrometers. It is designed to withstand the harsh conditions of industrial and outdoor environments while providing the accuracy expected from a lab-grade instrument, using only 2 mL of sample.
- Accurate density measurement on-site.
- Robust IP54 housing protects components.
- Requires only minimal sample volume (2 mL).

Features
- Rugged and Splash-Proof Design (IP54): Features a leak-proof sealed housing and additional rubber protection, ensuring the instrument withstands shocks and spills common in industrial and outdoor environments.
- Intrinsically Safe Models Available: The Ex and Ex Petrol versions are the only truly intrinsically safe portable density meters on the market (Ex marking [Ex] II 2 G Ex ib IIB T4), allowing for safe measurement of flammable chemicals and petroleum products in hazardous locations.
- Integrated Viscosity Correction: Automatically compensates for the influence of a sample’s viscosity on the density result, delivering reliable accuracy even when testing highly viscous materials (up to 300 mPa•s).
- Wide Temperature Operation: Capable of measuring samples with temperatures up to 100 °C, providing quick decision support for processes like hot wort measurement in brewing.
- Simplified Data Traceability: Stores up to 1024 measurement results with time stamps and includes both Bluetooth® and RFID interfaces for quick sample identification, customized measurement settings, and wireless data exchange.
- Smart Oscillator Placement: The patented design ensures that gas bubbles automatically move outside the measuring cell, which is crucial for reliable results when measuring samples like fermenting beer or highly carbonated beverages.

Software
The DMA 35 operates primarily using its internal firmware and preinstalled concentration units, eliminating the need for external calculation software for basic measurements. It includes a standard Bluetooth® interface which allows for convenient, direct wireless data exchange (in CSV or TXT format) with a PC or printer, and it is compatible with the optional AP Connect software for advanced data management and centralization.
FAQs
How does the DMA 35 replace traditional glass hydrometers?
The DMA 35 uses the oscillating U-tube principle to measure density digitally, offering lab-grade accuracy (0.001 g/cm³) in seconds, while being significantly more durable, requiring only 2 mL of sample, and providing built-in temperature correction.
What is the main difference between the DMA 35 Standard and Ex versions?
The Ex (Explosion-Proof) versions are specifically certified as intrinsically safe ([Ex] II 2 G Ex ib IIB T4), making them the only market option for safely measuring flammable chemicals and petroleum products in explosive, hazardous areas.
Can the DMA 35 be used to measure hot samples?
Yes, the instrument is engineered to perform density measurements on samples with temperatures ranging from 0 °C up to 100 °C, making it suitable for quality checks on hot liquids like wort in brewing.
Does the instrument require cleaning after every sample?
Yes, the measuring cell should be cleaned and dried between samples to ensure accuracy. The DMA 35 is designed for easy self-maintenance with a visible inspection window and a simple pump mechanism for quick, self-performed cleaning procedures.
What is the storage capacity for measurement data?
The DMA 35 has extensive internal memory capable of storing up to 1024 complete measurement results, along with timestamps and 250 programmable sample IDs for full traceability in the field.
